FERDINAND HERB, OF SUPERIOR,

com-em:

Be it known that I, FERDINAND HERB, a citizen of theUnited States,residing. at Superior, in the county of Douglas and State of Wisconsin,have invented a new and useful Nursing-Bottle, of which the following isa specification.

This invention relates to nursing bottles and is more particularlydesigned as an improvement upon the structure described and claimed inPatent #803590 issued to me on November 7, 1905.

In order to permit air to enter the bottle I otherwise than through theopeningin the collapsmg,

nipple, and thus prevent the nipple from it has heretofore beennecessary to form a longitudinal incision within the end of the bottleneck. This incision however is hard to clean properly and moreover-creased in thickness and weakens the bottle.

The object of the present invention is to provide a bottle whichdispenses with such an lncision without however interfering with theadmission of air into the nipple.

A further object is to provide such a means which does not weaken thebottle, but, on the contrary, tends to reinforce'it.

With these and other objects in view the invention consists of certainnovel details of construction and combinations of parts hereinafter morefully described and pointed out in the claims.

In the accompanying drawings the preferred form of the invention hasbeen shown. In said drawings ;Figure 1 is a perspective view of aportion of a nursing bottle having the present improvement thereon. Fig.2 is a longitudinal section through the upper portion of the bottle andshowing, by dotted lines, a nipple in engagement there"- with. Fig. 3 isan end view of the neck of the bottle. Fig. 4 is a View of aconstruction slightly different from that shown in the other figures.

Referring to-the figures by characters of reference, 1 designates abottle neck having an annular extension or flange 2 designed to beengaged by the large end of an ordinary rubber nipple such as has beenindicated by dotted lines at 3. As shown in Figs. 1 and 3 a portion of.the wall of the neck 1 may, if desired, be gradually interminate in aprojection or shoulder 4 which extends longitudinally of the upperportion of the neck and upon the outer side and the free end ofWISCONSIN.

the flange or enlargement2. A substantially L shaped groove or recess isthus formed between the shoulder and the adjoining. faces of theenlargement 2, this recess gradually diminishing thereof.

By providing a shoulder such as described it will. be. apparent thatwhen the large end of a rubber nipple is placed-on the neck the rib orshoulder 4 will hold a portion of the inner surface of the nipple :outof contact with the neck, thus forming an air' vent or passage throughwhich air is free to pass into the nipple. Inasmuch as the groove orrecess is produced by extending a shoulder radially. from the neck ofthe bottle it will be obvious that the same can be very readily cleanedby means of a brush or'the like and in no wise weakens the constructionof the bottle but, on the contrary, reinforces that portion of thebottle on which the shoulder is located.

If preferred, and as shown in Fig. 4, the projection may be in the formof a well defined rib' 5 forming a substantially L or V-shaped groove orrecess at each side so that when a nipple is fitted on the bottle an airpassage will be provided-at both sides of the rib. These grooves orrecesses gradually diminish in depth toward their lower ends. r

It will be understood, of course, that by shifting the nipple so as toextend below the rib or shoulder, air will not enter the nipple by wayof the recesses formed along the rib or shoulder. However, by shiftingthe nipplealong the rib or shoulder so as to expose the lower extremityof said rib or shoulder a minute quantity of air will be tle. By furtheradjusting the nipple toward the ends of the bottle neck the quantity ofair admitted in this manner can be increased.

By providing a device such as herein described the nipple is preventedfrom collapsing and the force necessary to withdraw the food therefromcan be controlled to suit the child. Moreover, by extending theoutstanding portion partly across the end' of the bottle neck, thenipple is prevented from collapsing against the end of the bottle neckto such anextent asto prevent the passage of air from the vent to theinterior of the nipple and bottle neck. k

It is of course to be understood that ribs in depth toward the lower endpermitted to thus enter the nipple and botand shoulders .of differentforms and proportions may be used and that various changes may be madein the construction and the arrangement of the parts Without departingfrom the spirit or sacrificing thevariable height and merging at oneend,

' into anoutst-andin portion upon the end of the bottle neck, sai lastmentioned outstanding portion extending inwardly to the mouth of thebottle.

2. A nursing bottle having a portion of its neck of gradually increasingthickness and terminating in a radially extending shoulder of variableheight.

3. A nursing bottle having a portion of its neck gradually increasin inthickness to form a radially disposed s oulder extending longitudinallyof the neck and partly across the end thereof, said shoulder being ofvariable height.

In testimony that I claim the foregoing as my own, I have hereto aflixedmy signature in the presence -of two witnesses.-
